Resend Inboxes Gives Agents Shared Mailboxes

Resend Inboxes adds API-first shared inboxes with threaded conversations, agent access through MCP or skills, and webhook-triggered workflows. Developers can create inboxes, route inbound email, assign threads, and reply programmatically, with a free tier covering up to three inboxes and 3,000 emails.

// ANALYSIS

Resend is evolving from an outbound email API into infrastructure for agent-native communication. The product’s strongest angle is giving agents durable email state and human handoff instead of treating inbound messages as disposable webhook payloads.

–Threading, labels, drafts, assignments, and replies make email usable as a workflow surface.
–MCP support lets existing agents operate inboxes without bespoke integration work. [Official MCP server](https://github.com/resend/resend-mcp)
–Webhook-triggered triage and drafting could automate support, recruiting, finance, and operations workflows.
–Inbound email is untrusted input, so production implementations will need sender validation, prompt-injection defenses, permissions, and human approval gates.
–The free tier makes experimentation accessible, while teams should evaluate retention, deliverability, and access controls before routing critical communications.

OPTD Adds Layerwise Supervision to LLM Distillation

On-Policy Transition Distillation extends on-policy distillation by matching teacher–student log-probability changes across transformer-layer segments during student-generated rollouts, not just final outputs. Across three backbones and eight mathematics, coding, and instruction-following benchmarks, it reports 89.2% teacher–student capability-gap recovery versus 74.9% for standard OPD.

VideoMaMa++ fixes flickering video matte seams

VideoMaMa++ is a mask-guided diffusion model from KAIST, Korea University, and Adobe Research that preserves fine alpha details across long videos. Its preserve/refine tokens, sliding-window inference, and reference anchors reduce edge flicker and transparency jumps between processing chunks.
